To all whom it may concern:

Be it known that. I, PASCAL J. Si-Irfllilhif, a citizen of the UnitedStates, residing at ineage. in the county of Cook and Stale of lllinois,have invented certain new and uset'ul Im n-ovcments in (ll:aning-Maehines, of wh ch the. l llowin aspeeil'ication.

My invention relates to scrubbing; machines and has for its primaryobject the provision of an improved scrubbing niaehine which shall haveimproved means for scrubb ng; rugs, carpets. and the like.

With the above and other objects in view this invention consistssubstantially in the combination, arrangement. and construction ofparts, all as hereinafter (lOSCllllGtl. shown in the accompanyingdrawings. which form a part of this specification and show the preferredembod ment. of my invention. and

I secure. the soiled rug to the outer periphery of a large cylinder. thewarp being; next to the cylinder and the nap away from it. The scrubbingand other cleaning devices are disposed adjacent the cylinder andconsiderably below the horizontal diameter thereof. As the cylinderrevolves, it earries the soiled rug downwardly into contact with thecleaning devices in such manner that the nap is scrubbed, leaving thewarp so dry that it does,- notshrink.

'll'iroughout the drawings, reference numeral 20 indicates the mainframe of my invention. A rug eylinde "31 is horizontally mounted bymeans of its axial shaft 22 for til) rotation in the frame 20. In Fig, 1is shown the. term oi mounting preferred by me, wherein the. shaft. 92is jonrnaled in the frame on a standard adjust able pillow blockindicated generally bv the numeral 23. For convenience, this pillowblock is mounted upon a hinge 2t, which is pivoted on the'l'nnne-\vo1'lt at 25. Standard adjustable pillow blocks 23, disposed atopposite ends of the cylinder, readily admit of the. adjustment of theentire. cylinder, while the hinges Q-latl'ord means whereby the cylinder21 may be swung out. of the position shown in Fig. 1 to allow readyaccess from above. to the parts of my invention disposed below thecylinder. At 26 is indicated any convenient fastening means for lockingthe free ends of the hinges 24 into fixed relation with the frame '20.The arrow indicated by reference numeral 27, in Fig. 1, shows thepreferred direction of movement of the cylinder Q1.

Generally indicated by the reference numeral 28, in Figs. 1, i and 5, isan adjustable fastening device for securing" the soiled rug to thecylinder 21. This fastening device comprises a longitudinal slot 29 inthe cylinder extending from a point adjacent one end thereof to a point.adjacent the other end. thereof. Two channel irons 30 and 31 terial,such as wood. Thebar 33 extends the length of the space 32 and is ofsuch size as to be movable within the space 32 preferably along the lineof the radius or the cylinder passing through it. Secured along theouter surface of the bar 33, and directly opposite the slot 29, is a rod34 of c0mpressible material, preferably rubber, extending the length ofthe bar 33. Pivoted to lugs 35 and 36, formed upon the channel irons- 30and 31, are a plurality of oscillating cams 37, shown in Figs. at and 5,the pivoting means being a small bolt 38 passing through both lugs andan aperture in the cam. The cams 37areso disposed with respect to thebar 33' that when oscillated simultaneously they wilLmove the bar in thespace 32 toward or away from the slot 29. These cams 37 are disposed atconvenient distances along the length of the bar 33 and are actuatedsimultaneously by a longitudinally recipro- Gating strip 39, to whicheach of them is pivoted. For the purpose of obtaining considerableleverage upon the cams 37, each of them bears an arm or extension 40slotted at its'extremity farthest from the pivot 38.

Studs 11 protruding from the sides of the strip 39 pass through theslots in the extremities of the arms 40 and form thus a drivingconnection between the cams 37 and the strip 39. The strip 39 may bereciprocated in any convenient manner, the preferred method being shownin Fig. 4, wherein an angle iron 42 is secured to tlie'channel irons 30and 31, and is in threaded engagement with a handled shaft 13, which isswiveled in any convenient manner to one end of the strip 39. The rug tobe fastened is generally indicated (in Fig. 1) by the reference numeral44, its warp side being numbered 45 and its nap side 46. In theoperation of the fastener 28, one end of the rug to be cleaned isinserted through the slot 29 into the space 32. The handled shaft 43 isoperated to create a tension upon the strip 39 and thus draw the earns37 into the position shown in dotted lines in Figs. e and 5, for thepurpose of forcing the bar 33 and the rod 3-l outwardly to cause the rod34 to pinch the inserted end of the rug 44 against the cylinder 21. Inaddition to pinching the rug. 4% and holding it in its inserted position in the slot 29, the compressible rod 31- completely clo the 29,making a watertight therewith. The rug e l i serving as. guides for theru side of the cylinder 21, and the warp of the rug will lie against theouter periphery of the cylinder.

Supported in any suitable manner upon the frame 20 are two guide rollers47 and 48 4:4 as it is drawn onto the cylinder by t e revolution of thecylinder in the direction of the arrow 27. For convenience intemporarily holding the end of the ru to be fastened near the cylinder21 (see l igs. 1 and 3) is provided a series of needle points '19projecting to-. ward the cylinder and secured to an angle bar 50, whichfinds its support in any suitable manner upon the frame 20. When a largerug is to be secured to the cylinder, it is drawn up over the needles 49and pressed down upon them, thus holding it in position adjacent thecylinder 21 while the extreme end of the rug is inserted through theslot 29. The revolution of the cylinder 21 in the direction of the arrowwill, without damage to the rug, draw it 03 the needle points 49. As aprotection to the operator from the sharp points of the needles 49, Ipreferably provide fiat springs 51, slotted as at 52 and secured to theangle iron 50 in such position that they may be pressed down at theirfree ends, causing their slotted portions to descendabout the needles 49and expose the needles for insertion in the rug. When the rug has beendrawn otl" the needles 49, each of the springs 51 rises from itsposition carried on the cylinder in the direction indicated by the arrow27, it passes over the roller 48 and approaches a valved feed pipe 53disposed below the cylinder, and which is supplied from any convenientsource with liquid soap, or other desired liquid cleaning.

compound. The feed pipe 53 extends longitudinally of the cylinder 21from a point adjacent one end thereof to a point adj t a the oppositeend thereof, and is provided with a plurality of valved openings 54 (seeFig. 8); The valves governing the feed of liquid soap from the feed pipe53 are shown in Figs. 1, 3, 6 and 7. In the construction of thesevalves, lugs 55 are provided on the outer side of the feed pipe 53 andprotruding laterally therefrom. To each lug 55 is pivoted, intermediateits extremities, a curved valve lever 56, one end of which is providedwith a closure 57 for the aperture 54, and the opposite end of whichcarries a rotatably'mounted roller 58. A compression spring member ofany suitable form is of the cylinder 21, the proximity being such thatthe thickness of the rug, as it passes between the cylinder 21 and theroller 58, os-

' cillates the lever 56 upon its pivot, thereby opening the aperture 5%and allowing liquid soap to pass outward from the feed pipe 59. Thisopen position of the valved apertures 54: is best shown by the dottedlines in Fig. 7. The'cylinder 21 is of such a length that rugs ofconsiderable width can be carried thereon, but it is an advantage of myvalved :t'eed pipe that when a narrow rug is to be scrubbed, only thosevalved apertures which are opposite the rug will be opened by thepassage of the rug upon the cylinder, the remaining valved aperturesstanding closed, thus preventing waste of the liquid soap or othercleaning compound. However, should a rug as wide as the full length ofthe-cylinder be inserted in my machine, all the valved apertures 54would be opened thereby, thus supplying liquid soap sufiicient for theentire surface of the rug. 1nasmuch as the action of the levers 56 andclosures 57 is non-adjustable, and the oscil lating of the levers 56opens the apertures 54 to their full extent, I provide adjustable meansfor limiting the passa re of liquid through the apertures 5-l byiurnishin a curved strip 60, preferably of metal, illsposed within thefeed pipe and adapted to be adjusted within the pipe to partially close,or fully close, if desired, the apertures The strip 60 isgiven a curveconforming to the inner periphery of the pipe 53 and is provided withoblique slots 61, which are engaged by studs 62 protruding from theinner surface of the feed pipe. Draw wires 63, secured to either end ofthe strip 60 and passing out of the feed pipe 53 through small aperturesprovided therefor, are the means I preferably employ for shifting thestrip 60 upon the studs 62. Any other convenient means may, however, beemployed. The shifting of the strip 60 causes one edge of the strip tooverlap the apertures 54 obstructing the passage of liquid therethroughas much as desire By thus obstructing the apertures 54, the quantity ofliquid emitted from the feed pipe may be properly regulated. The supplyof liquid soap, or other cleaning compound, is brought to the feedpipe-53, preferably from its end 53 (see Fig. 3) under'sulticient headto cause it to flow freely through the apertures 54, the opposite end ofthe feed pipe bein closed by a plugfil which is apertured for tiepassage of the draw wire 63, if such draw wire beused. The draw wire 63fits the aperture in the plug 54: so closely as to prevent the leakageof liquid through. the plug.

Three cylindrical rotating brushes 65, (i6 and (37 are disposed belowthe cylinder 21 and in such proximity thereto that, when rotated, theywill scrub the nap 46 of the rug 44- as the rug, borne by the cylinder,is carried past them. The brushes preferably rotate in the directionsindicated by the arrows 65", 66 and 67. Chamber-ed inclosures 68 and G9are provided for the brushes for the purpose of collecting liquidsthrown from the brushes by centrifugal t'orce. T he chamber 69, whichincloses the brush 67, is preferably provided with a drain cock-70. itsthe valved apertures in the feed pipe 53 are opened by the passing ofthe rug ll, the soap which is emitted from the feed pipe drops from adrip board 71, which is given a slight pitch downward from the feed pipeto a point where the soap will drop otl' onto the brush 65. The rotationofthe brush 05 carries the liquid soap thus dropped upon it up to thenap ll of the passing rug, wetting the napof the rug and simultaneouslyscrubbing it in the direction indicated by the arrow (35. In the furtherpassage of the rug, it encounters the brush 66 rotating in an opposite?direction, as indicated by the arrow 66; Thus it will be seen that inpassing the two scrub brushes 65 and (56 the nap all} of the rug hasbeen scrubbed in each direction. The bottom of the chamber (38 is inclose proximity to the brushes 65 and 66, and is given a slight pitchcorresponding to the dill'crencc in level of the axes of these brushes,from which it will be seen that whatever liquid soap is thrown from thebrush 65 will drain down toward the brush 66 and be carriedthereby up tothe nap 46 of the rug. In this way the brush (it; receives its supply ofliquid soap. After the soap scrubbing given to the rug by the brushes(55 and (36, it is desirable to scrape from the rug as much as possibleof the liquid soap which adheres thereto. For this purpose I provide adouble set of soap scrapers 72 and 73, held in contact with the rug bybeing secured to an angle iron 74, shown in Figs. 1, 3, l1 and '12.These scrapers are 15 preferably formed of a tempered metal,

such as steel or brass, and are disposed preterably in parallel lines,the lines being spaced from each other, and the blades being spaced fromeach other in the lines. This 120 spacing provides for rapid draining ofthe dirty liquid soap scraped from the rug, the

liquid dropping into the chamber 69 and blades 73 to the angle iron 7 4,and the spacing of the lines of scrapers from each other may beaccomplished in any desired manner, such, for instance, as theemployment of collars 76 and bolts 77 somewhat longer than the bolts 75.To ermit a firm seating of the collars 76 against the angle iron 74, Ipartially cut away the lower corners of the blades 73, as at 78 in Fig.11. For adjustment of the scrapers 72 and 73 toward or away from thecylinder 21, I provide slots 79 for the passage of the bolts 75 and 77.Obviously, by a loosening of the bolts, the

blades may be raised or lowered, and the bolts again tightened againstthem.

The next part of my mechanism acting upon the rug as it travels along onthe cylinder 21 is a water pipe 80, shown in Figs.

. 1 andB, having a plurality of apertures 81.

The water pipe 80 is disposed any suitable distance from the cylinder21, lies preferably parallel thereto, and the apertured portion thereofextends approximately the length of the cylinder. It is adapted toreceive water under a suitable pressure, preferably from its end 82, andthe apertures 81 are so disposed as to project the water from the pipe80 against the nap 46 of the rug 44. Control of the pressure and theamount of water in the pipe may-be provided for in any convenientmanner. the exact method not being here shown. The pipe 80 is preferablydisposed between the scrapers 73 and the brush 67. As the rug passesfrom a position opposite the water pipe 80, it is scrubbed by the brush67 by a backward motion. as indicated by the arrow 67, the water thrownofi' by the brush 67 draining downwardly into the lower portion of thechamber 69 and being drawn off, at the will.

of the operator, through the drain cock 70. After being scrubbed by thebrush 67, the, rug, in its passage upon the cylinder, is scraped byanother double set of scrapers 83 and 84. similar to the scrapers 72 and73, and sim larly disposed with relation to each other. This double setof scrapers is pref e'rably secured to an upwardly extending portionofthe side of the chamber 69, and suflicient room is allowed beneath thescrapers 83 and 8. for drainage of water scraped from the rug. Securedparallel to the line of scrapers 84, and just outside of it, is ayielding wiper 85 of rubber or similar material, having contact with thesurface of the cylinder 21, except where the rug covers the cylinder.This yielding wiper 85 removes the liquids from the cylinder, keepingthe surface thereof dry for contact with the warp side of the rug.

In order that the rug, in its passage on the cylinder. may not bebuckled or doubled upon the cylinder by the action of the brush 65,which, as indicated by the arrow travels in a. forward direction againstthe means rug, I provide, preferably, a series of stiff wire holders 86,shown in Figs. 1 and 3, which serve to hold the rug in contact with thecylinder, and about which the bristles of the brush 65 readily pass.

The liquid soap and the water thrown against the rug in its travel uponthe cylinmay be formed in any suitable member de-.

sired having attachment to the frame 20, or in any other suitable mannersupported.

The channels 88 are provided with apertures 88*, .whereby the liquidcollected in the channels may drain downwardly into the chambers 68 and69. As a further protection against the dripping of liquid from the endsof the cylinder, I provide two strips of a packing material 89, such asthick felt, which press closely against the lower half of the cylinder21. The strips 89 are seated in channels 90, provided either in the endsof the chambers 68 and 69 or in any other convenient member founddesirable, and they are maintained in contact with. the lower portion ofthe cylinder by flat springs 91, which are secured to the bed of thechannel and press upwardly strips 89.

Power is applied to my rug scrubbing ma against the 'chine in anydesired manner, the exact method of application not being here shown. Inpractice, it is desirable to have the cylinder 21 travel at a peripheralspeed of six feet per minute and to have the brushes 65, 66 and 67rotate from 200 to 400 revolutions per minute, though, of course, I donot limit myself in any way to these speeds. In the operation of mymachine, a rug or carpet to be scrubbed is brought with its end towardthe machine, the end is raised, and the weightot the rug held 06' of thedoor by the insertion alhng its width of the needles 49. Thc'cXtreme-cndof the rug is then in sertcd through the slot 29 into the space 32, theslot 29 being preferably in a position adjacent but slightly above theroller 48.

66 and G7 and the water pipe 80. The rug is so secured to the cylinde'21 that its nap is exposed to the action oF the brushes and the scrapersheretofore described, while its Warp lies against the outer periphery ofthe cylinder. Power is now applied to the machine. and the cylinder 21begins to revolve in the direction indicated by the arrow :27 (see Fig.1). As the rug passes the feed pipe the rollc s :38 ride up upon itsnap, thus opening the apertures 54 in the pipe 53, ,allmving snap toflow down the drip board 71 to the rapidly revolving brush 65. Ast-he'rug proceeds, it passes oetween the wires 86 and the cylinder, andis violei'itly scrubbed by the brush 6:"), the soap :troin the feed pipe53 being thrown against the nap of the rug by the rapidly whirlinghrush. The rug then passes onward to the brush G6, which scrubs the napin an opposite direetion to that of the hrush 65. The hrush 66 alsoapplies more liquid soap to the. nap ot' the rug, having received asupply of soap from the lower portion of the i'rhan'iher (5S.

. itroceeding farther, the rug is scraped by the double set of scrapersTil and 73, which, heing constructed of a tenn'iered metal, hendsuil'iciently'to avoid sci; ping the nap of the rug from the warp but,nevertheless, press suiliciently hard upon the nap to wipe therefrommost of the liquid soap which has been applied. The head oil water isnow turned into the water pipe 80, and jets of water are g rejectedagainst the rug; throughout its width from the apertures 81. of thewater pipe, thus rinsing, the nap of the rug; and Washing away stillmore ot the soap which has been applied. The nap of the rug now beingWet Withwater, it necessary to remove asmnch as possihle of the water,and to accemplish this the rug ein':oi.inters the brush 67, which,rotating in the direction indicatedhy the arrow (57, dashes from the rugall the loose water held by the nap. The double set of soapers 83 and 84now press upon the rug for the purpose oi pr out as much possible of thewater still retained lrv the map. The yielding scraper 85 readil v hendsto allow the passage of the rug and wipes a slight amount of waterthere'lrom. flow over, the scraper S5 is provided 'athcr to perform thetlunetion ol, wiping dry the outer surtace of the cylinder than for the}')U.l'POS(. of turtluir (.lrying the rug after it has been scraped. Thescraper 85 thus keeps the outer surface of the cylinder drv at all timesfor the instant appii ation oi. a rug. From the for going description,it ohvinus that no liquid is applied to the warp t' the rug, thuspreventing; that shrinkage the rug which takes place in the ordinaryihhing process.
